[1][2] Six locomotives with a 0-10-0 Decapod type wheel arrangement were built in 1910 by Henschel & Son of Kassel in Germany for a French Colony in Africa.

The total weight of the engine and tender in full working order was 74 long tons (75,190 kilograms) and it had a tractive effort of 16,220 pounds-force (72.2 kilonewtons) at 75% of boiler pressure.

[1][2] To allow side-play in curves, the axle boxes of the leading and trailing coupled wheels had no inside flanges.

According to one report, their utilisation as mainline engines rapidly resulted in the development of excessive side-play to the extent that the tyres eventually cut into the spring hangers.

[1] The locomotives were numbered in the range from 101 to 106 and were placed in service on the Südbahn line from Lüderitzbucht via Seeheim to Kalkfontein, where they formed the mainstay of motive power.
